The second largest motive power depot and repair facility on the Midland Rail was north of the station.[4] In 1861 a collision occurred at a siding near the station in which 16 people were killed and 317 were injured.

Trains from south of the River Thames on the extended Thameslink network may call at the station from 2018.[8]

After the bay platforms at Blackfriars station closed in March 2009, Southeastern services which previously terminated at Blackfriars were extended to Kentish Town (off-peak), or St Albans, Luton or Bedford (peak hours).[9]

A major upgrading of the whole Thameslink line infrastructure is underway, for expected completion by 2018. However, the four platforms at Kentish Town station are not being extended from eight to 12 carriages because of road bridges at each end which cannot be relocated,[10] so only services that continue to be served by eight-car trains will be able to call there. The only other Thameslink stations north of the River Thames remaining with eight-car platform lengths will be Hendon and Cricklewood, which are sited either side of a possible new Thameslink station at Brent Cross.
